    • A base (10) has a substantially cylindrical plug (12) penetrated by two leads 14. A piezoelectric oscillator (24) is secured to and supported on ends of the two leads by supports (26). The supports (26) are formed from solder having as high lead content of more than 60% by weight, preferably 85 to 98% by weight. A cap (28) open at one end is fitted on the piezoelectric oscillator (24). The plug (12) seals the open end of the cap (28) and forms a gas-tight casing, thus forming a piezoelectric oscillator unit with piezoelectric oscillator (24) held gas-tight in the inside. The high lead content solder is soft and has a low Young's Modulus, so that it can disperse stress when the piezoelectric oscillator experiences. It is thus possible to evade stress concentration on the piezoelectric oscillator (24) and improve shock resistance. A layer of a solder with a lead content of 60% by weight or less or of tin or a tin alloy, is formed on the surface of the leads (14), and ensures solder wetting property.
    • 基座(10)具有由两个引线14穿透的大致圆柱形的塞子(12)。压电振荡器(24)通过支撑件(26)固定并支撑在两个引线的端部上。 载体(26)由铅含量高于60重量%,优选85-98重量%的焊料形成。 在一端开口的帽(28)安装在压电振子(24)上。 插头(12)密封盖(28)的开口端并形成气密的壳体,从而形成压电振荡器单元,其压电振荡器(24)在内部保持气密。 高铅含量焊料是柔软的并且具有低的杨氏模量,使得当压电振荡器经历时它可以分散应力。 因此可以避免压电振子(24)上的应力集中并提高抗冲击性。 在引线(14)的表面上形成铅含量为60重量%以下的锡或锡或锡合金的焊料层,并且确保焊料润湿性。
